Concrete balls?I like how they tried deterring people from doing something dangerous by making it more dangerous.Seriously, I've never heard about people actually using deathtraps before.People tend to stick to non-lethal things, like electrified fences, instead of using orbital laser cannons.

Cameron's delivery is very dry. He needs someone like Alex who we've seen can do something with that. I think he'd pair well with someone like Matt or Paul.

Tally would probably pair well with James or Andy. (The obvious pairing is Kathleen, because she pairs well with just about everyone, but I think Tally with either James or Andy would be an interesting pair)

In the steam era they called them tell-tales to warn/knock down anybody on the roof that a tunnel was coming, but they were just heavy rope with knots tied at the bottom, not concrete for crying out loud.

(I've been holding on to that information for many years thanks to my Dad being a train nut. TOTALLY WORTH IT!)
